Between Oct. 16 and Nov.12, FEC filings show that Martin raised $2.4 million to Chambliss' $1.9 million.

The National Republican Trust PAC (GOPtrust.com) launched a new TV ad tying Martin to Obama and Pelosi's plan for new taxes on the wealthy, abortion rights and gun control.

Liberal activist groups like NARAL Pro-Choice America, the Service Employees International Union, the League Of Conservation Voters Action Fund and the Democratic Senatorial Campaign Committee have sent more than $1.7 million to help Martin.

Once thought a safe seat, the GOP is no longer sure about Georgia. Republicans have already seen the Alaska seat held by Republican Ted Stevens slip away, and Republican Norm Coleman's lead in Minnesota has dwindled to less than 200 votes.
